Adding PHP support to Nginx.

In the last post, I show how to install and configure Nginx on CentOS. In this post, I will show you how to add PHP support to that installed Nginx web server.

There are two ways to add PHP support to Nginx: One by Using PHP-FastCGI and the other way is to use PHP-FPM. Using PHP-FPM is the simple way to add PHP support to Nginx and the way that i will demonstrate on this blog.

Enabling REMI

First, we will need to add the REMI repository to the system. To do this we will download and install the remi-release rpm (notice that EPEL needs to be available or you will have dependency issues).

Download the remi-release rpm:

[[email protected] ~]# wget http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

Install the remi-release rpm:
`[[email protected] ~]#rpm -ivh remi-release-7.rpm

We are going to install yum-utils to use yum-config-manager on the system to enable the required repositories:

[[email protected] ~]# yum install yum-utils -y

Enable the repos:

[[email protected] ~]# yum-config-manager --enable remi

[[email protected] ~]# yum-config-manager --enable remi-php56

[[email protected] ~]# yum clean all

Installation and configuration

Now we are going to install php-fmp y php-mysql from the previously enabled repositories:

`[[email protected] ~]# yum install php-fpm php-mysql

Now we are going to edit php.ini and change cgi.fix_pathinfo=1 to cgi.fix_pathinfo=0 . This change will be done to reduce the risk of PHP processing the wrong files that could lead to a security exploit.

[[email protected] ~]# vim /etc/php.ini

On that file search and replace cgi.fixpathinfo=1 to cgi.fixpathinfo=0. Verify that there is not a commentary (;) on the front of the line, this will invalidate the change that you just did.

Now we are going to modify: /etc/php-fpm.d/www.conf

[[email protected] ~]# vim /etc/php-fpm.d/www.conf

We are going to change :

listen = 127.0.0.1:9000

to :

listen = /var/run/php-fpm/php-fpm.sock

Now we are going to enable and start the php-fpm service:

[[email protected] ~]# systemctl enable php-fpm.service

[[email protected] ~]#systemctl start php-fpm

Check the status of the service:

[[email protected] ~]# systemctl status php-fpm

Configuring Nginx to process PHP pages

At this point we have PHP installed on the server and runnig. The next step will be to add the PHP support to Nginx. In my case i will fo it to the virtual hosts entries by adding:

location ~ \.php$ {  
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;  
fastcgi_index index.php;  
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;  
include fastcgi_params;  
}

After the change, restart the Nginx service and test that you could serve .php pages.

[[email protected] ~]# sudo systemctl restart nginx.service

Add to your virtual host directory a file and name it info.php with the next code:

[[email protected] ~]# vim info.php
<? phpinfo(); ?>  

After this, you should be able to browse to this page and see all the PHP info from your server.
